Description

The invention relates to a hand press for vegetables or fruits, in which two levers are hinged together and serve at least with part of their length as handles, one lever having a press chamber provided with through openings in the bottom for the material to be pressed for inserting the material to be pressed out and the another has a pusher penetrating into the press chamber when the levers are pivoted, at least two press chambers being provided.

Hand presses of this type are mainly used for pressing garlic and onion for seasoning the food.

US Pat. No. 1,762,031 describes a press of the type mentioned, in which one lever divides one into two halves by means of a central cutting wall Press room owns.

A fruit press has become known from US Pat. No. 1,840,182, in which a press container with two press chambers separated from one another by an intermediate wall is fastened on a stand and is provided with a manually operated lever which is articulated on the press container and on which two pushers are connected by a common lever connecting forked arm are articulated. The fruit to be expressed e.g. an orange is cut in half until the halves are still connected to a piece of the peel. The two halves are then placed in the press rooms, the contiguous rest of the shell coming to rest on the partition. Finally, from DE-AS 1 255 877 a device made of plastic for cutting and pressing fruits and vegetables with a press foot has become known, on which a press lever is pivotally mounted, which carries a press plate which, when the press lever is actuated, in one arranged in the press foot moved against an interchangeably arranged cutting or perforated insert.

With the known devices, the fruit or vegetables can only be squeezed out with a single degree of fineness. However, it has been shown that depending on the preparation and / or the fruit (garlic mostly finer, onion usually coarser, which is why two different presses were previously required) - grilled, cooked, fried etc. - and depending on the type of food Adding the pressed material, e.g. different degrees of fineness are desired as wort, garnish etc. The degrees fine or coarse are usually sufficient.

The present invention has for its object to avoid the disadvantages of the known devices to create a hand press, in which the material to be pressed can be pressed simultaneously and in any sequence finely and / or roughly.

This object is achieved in a hand press of the type mentioned at the outset in that, according to the invention, the press rooms are provided with different openings in the floor.

In order to also offer the possibility of cleaning the holes in the floor of the press rooms, according to a further feature of the invention, at least one of the levers is provided with cleaning pins, wherein several sets of cleaning pins can be provided, of which one set corresponds to an opening group, so that no pivoting of the levers against the pressing direction penetrate the pins into the openings of the pressing space used.

The use of cleaning pens is well known from AT-PS 294 351. However, only one type of hole is provided in the known device, so that only one type of pin is required. If such a type of pin were used in the hand press according to the invention, the pins could only clean the set of holes which is intended for the set of pins used, while the other holes could be insufficiently cleaned, or the pins could have a larger diameter than the holes in them do not penetrate.

The hand press according to FIGS. 1 to 3 consists of two double-armed levers 1, 2 articulated at 5 with arms of unequal length, of which the longer 1 ', 2' as handle parts and the shorter 1 "or 2" as pushers 3 or sieve part 4 serve. The handle part 1 'is connected to the handle 3 diagonally opposite the joint 5 on the joint 5 also formed as a pusher 3 '. Likewise, the grip part 2 'is provided with a sieve part 4' opposite the sieve part 4, following the joint. The sides of the pushers 3 and 3 'facing the sieve parts 4, 4' are each provided with a plunger 6 and 6 ', respectively. The joint provided at 5 can at most be detachable, so that the two levers 1, 2 can be separated from one another for cleaning purposes. The sieve parts 4, 4 'each have a bottom 7, 7', the bottom 7 and the plunger 6 and the bottom 7 'and the plunger 6' coming to lie on one another in the pressing position. Walls 8, 9, 11 and 8 ', 9', 11 'protrude laterally and at the front from the floors 7 and 7', which, together with the associated floors 7 and 7 ', form a pressing chamber 12 and 12' for inserting the material to be pressed out Serve good. In this case, the bottoms 7 and 7 'are provided with openings 10 and 10', for example round holes, the openings of one floor being larger and / or different from those of the other floor. The two pushers 3, 3 'have, on their side facing away from the openings 10, 10' in the pressing position, pins 14 and 14 ', respectively, which in the extended position of the two levers 1, 2 shown in dash-dotted lines in FIG. 1 from the rear of the floors 7, 7 'penetrate into their holes 10, 10' and thereby press the residues remaining in the openings after the material has been pressed out into the pressing chamber 12, 12 'and thus clean all holes at the same time.

The described hand press works in the following way: If the two handles 1, 2 are pressed together after inserting a product to be pressed into the pressing chamber 12 in the directions of the arrows A, B shown in FIG. 3, the piston 6 presses the pressing material through the bottom 7 or its openings 10 or holes. If the levers 1, 2 are brought into a stretched position according to FIG. 2, the pins 14 penetrate into the openings 10 and press the remnants therein into the press chamber 12. If a good is now to be expressed in the press chamber 12 ', the device is turned off the position shown in Fig. 3 about its longitudinal axis by 180 °, so that the bottom 7 'comes to lie down and the piston 6' penetrates from above into the press chamber 12 '. The rest of the process is the same as that previously described.
